RSCS Generation Procedure
CREATING THE LAXLINES COPY FILE
The LAXLINES COPY file defines the virtual device addresses of the
telecommunications line ports (attached to the RSCS virtual machine)
which may be shared among the various active links. Such line ports
must be switch able, and the links which are to use these line ports must
have switched line ports available at their remQte stations.
The LAXLINES COpy file consists of a list of GENLINE macro
statements, one for each line port. The format of the GENLINE macro is
as follows:
r , I GENLINE I LINE=vaddr , L __________________ --____________ _
LINE=vaddr
is the virtual device address of a switched telecommunications
line port available to RSCS. CREATING THE TAGQUEUE COPY The TAG QUEUE COPY file specifies the total number of virtual storage tag
slots to be available to RSCS. The format of the GENTAGQ macro is:
r I GENT AGQ
L Nurr=totslots NU"=totslots is a decimal number to 512 that defines the total
number of . virtual storage"tag slots to'·be made available to RSCS for storing inforntion on 'f·iles enqueued for
transmission or received froa! remote Files which

automatically accepted .. a. t a later time as virtual
storage tag slots You must specify a numbet for totslots that is at least as
large as the sum of linkijtag slots or implied by the
KEEP=holdslot operand of all the macros.
Generation Procedure forRSCS Before you perform the RSCS generation procedure, be sure you have the
following: • The V!/370 system PUT tape • A V"/370 directory entry for your RSCS virtual machine • A V"/370 directory entry for the software system support
machine (for example, the MAINT entry supplied with the
starter system directory).

RSCS Generation Procedure You can use a 2314, 3330, 3340, or 3350 disk as the RSCS system disk.
The RSCS nucleus occupies two cylinders on a 2314 or 3340, and one
cylinder on a 3330 or 3350 disk.
The following system generation procedure for RSCS assumes you have
the "AINT virtual machine supplied with the V8/370 starter system in
your VM/370 directory. STEP 1. LOG ON AS MAINT AND IPL CMS To build the RSCS nucleus, you must log on the software system support
virtual machine (MAINT) and IPL the CMS system.

initiated by issuing the commands:
access 191 c
vmserv restart 5749010 rscs noipl
The keyword "rscs" allows the procedure to load wha t is required
(from the system PUT) for RSCS. You are prompted for 'various information concerning your system
(including staging area addresses and the service that you want
applied). Respond 'NO' when asked if you wish service for IPCS. Service for IPCS has already been applied. The user memOs 'and the PUT document should be referenced concerning the application of service with
the VMSERV EXEC. After service has been applied, you will receive this message: DO YOU WISH TO BUILD RSCS SYSTEM -- RESPOND (YESINO) You must respond "no". STEP 3. FORMAT THE RSCS SYSTEM DISK You must link to the RSCS system disk and format it. If you used the VM/370 directory entry for the RSCS virtual machine supplied with the
starter system, your LINK command is:
link to rscs 191 as 195 w pass= password
This makes the Rses system disk (address 191 in the Rses virtual
machine) available at virtual address 195 in the MAINT virtual machine.
Remember the address you specify for MAINT. You must use this same
virtual address later in the RSCS generation procedure (you use 195 when
you invoke GENERATE again to build the RSCS nucleus in Step 7). Then,
format the RSCS system disk.
